　　T: There are some differences in table manners between the western countries and China. If an American or Englishman invites you to dinner, you’d better arrive on time. You can arrive a few minutes late but you can’t arrive early. While eating, you’ d better put your table napkin on your knees not around your neck if there is any. In China, we usually serve dishes first and then soup, while in the West, people prefer to serve soup before dishes. In China, hosts are always toasting wine and picking up food for their guests again and again but in the west especially in America, hosts only offer food once. If you want to have more, just help yourself to it. Don’t pretend to be refined. The host won’t offer a second time. Hosts like their guests to help themselves. If you don’t know the taste of a dish, you can taste a little. You mustn’t refuse what your host offers you. If you don’t like it indeed, you can honestly say; Sorry. I’m not used to that. Thank you. But you must eat up all the food put in your plate, finish all the wine put in your glass. Don’t make any noises while eating. Don’t put your plate close to your mouth or put you mouth into the plate. You should help your host/ hostess to set the table before the dinner. After the meal you ought to offer your host the help to clear the table.
